Expose bulk_size as track parameter (elastic#63)

With this commit we expose the track parameter `bulk_size` for the challenge
`index-logs-fixed-daily-volume`. This also eliminates the need for the
challenges `bulk-size-evaluation`, `bulk-size-evaluation-mini` and
`bulk-size-concurrency-evaluation` as they can be simulated using the track
parameters `bulk_size` and `bulk_indexing_clients`.

 ## Available Challenges
 
-### bulk-size-evaluation
-
-This challenge performs bulk-indexing against a single index with varying bulk request sizes, ranging from 125 events/request to 50000 events/request.
-
-The table below shows the track parameters that can be adjusted along with default values:
-
-| Parameter | Explanation | Type | Default Value |
-| --------- | ----------- | ---- | ------------- |
-| `number_of_replicas` | Number of index replicas | `int` | `0` |
-| `shard_count` | Number of primary shards | `int` | `2` |
-| `bulk_indexing_clients` | Number of bulk indexing clients/connections | `int` | `16` |
-
 ### shard-sizing
 
 This challenge indexes 2 million events into an index consisting of a single shard 25 times. After each group of 2 million events has been inserted, 4 different Kibana dashboard configurations are benchmarked against the index. At this time no indexing takes place. There are two different dashboards being simulated, aggregating across 50% and 90% of the data in the shard.
